不锈钢310—310S钢材性能

钢制 310/310S是一类莱氏体密序钛，在 2000ºF 的保守循环式不利因素下具备更高的隔热潜能。此种钢具备十分高的镍和铬浓度，与常用的莱氏体钛（如 304 型）较之，具备完全相同的抗腐蚀、charged代谢潜能和留存Villamblard比率的常压热量。310 钢制时常在高温下采用覆盖范围，在 -450°F 下具备出众的延展性和更低的介电。隔热性更高的铬浓度——意在提升高温操控性也为那些车牌号提供更多了十分好的防油易燃。PRE 约为 25，耐湖水性约为 22°C，与 316 级十分相近。在高温自然环境中，它具备较好的水溶性和耐轧制性。在常压下可耐热磷酸氢二钠和仅约 425°C 的熔化氨。
